Does using the right motor oil have anything to do with engine life ?
The single most important thing you can do to get long life from your engine is to change your engine oil and oil filter as often as recommended by your car manual. Motor oil that properly lubricates the engine system during the initial part of life can become thick towards the later stages of its sump life. It then cannot flow as required and also blocks the oil filter. This may cause engine damage and seizure in extreme cases.
